Dee Williams was diagnosed with a heart condition when she was 41. Faced with her mortality, she radically changed her life. She built a tiny house and reduced the number of things she owns to about 300. She wrote a book about her experience, The Big Tiny, which came out today.

[T]ime is precious, and she wanted to be spending hers with the people and things she truly loved. That included the beautiful sprawling house in the Pacific Northwest she had painstakingly restored—but, increasingly, it did not include the mortgage payments, constant repairs, and general time-suck of home ownership. A new sense of clarity began to take hold: Just what was all this stuff for? Multiple extra rooms, a kitchen stocked with rarely used appliances, were things that couldn’t compare with the financial freedom and the ultimate luxury—time—that would come with downsizing.

Deciding to build an eighty-four-square-foot house—on her own, from the ground up—was just the beginning of building a new life. Williams can now list everything she owns on one sheet of paper, her monthly housekeeping bills amount to about eight dollars, and it takes her approximately ten minutes to clean the entire house. It’s left her with more time to spend with family and friends, and given her freedom to head out for adventure at a moment’s notice, or watch the clouds and sunset while drinking a beer on her (yes, tiny) front porch.
